ABSTRACT

Use in cosmetic lotions a dispersion solution of super-fine noble metal particles obtained by burning a mixture gas of oxygen and hydrogen in high-pressure water and using the combustion gas to melt noble metal and thus causing super-fine noble metal particles to micro-disperse in water, wherein such production process is implemented using an apparatus for producing a cosmetic lotion that comprises a pressure-resistant container equipped with a high-pressure water tank, an injection nozzle for mixture gas of oxygen and hydrogen, a noble metal bar, an ignition device and a combustion chamber.

FIELD OF THE INVENTION

This invention relates to a cosmetic lotion made of high-function waterin which super-fine noble metal particles are micro-dispersed, a methodand apparatus for producing the same, as well as a cosmetic materialcontaining, as its water content, such high-function water in whichsuper-fine noble metal particles are dispersed.

BACKGROUND OF THE INVENTION

Noble metals possess excellent gloss and corrosion resistance and aretherefore used widely in accessories such as rings, necklaces, braceletsand earrings. Due to their corrosion resistance, heat conductivity andother physical properties noble metals are also utilized broadly inindustrial applications such as electrodes and electrical contactmaterials used in electrical and electronics products and energysystems, and also in articles of daily use such as eyeglass frame andclock casing. The applications of noble metals are expected to growfurther.

The conventional technologies applying noble metals, for example silver,include a water filter utilizing the antibacterial properties of silver(Japanese Patent Application Laid-open Nos. 7-303809 and 7-195086),dispersion solution of fine particles offering both antibacterial andantifungal effects (Japanese Patent Application Laid-open No. 7-304616),and composition for anti-electrostatic processing for preventingelectrostatic in fabrics and leather products (Japanese PatentApplication Laid-open No. 11-172154). A coating solution for shieldingsolar radiation that utilizes ruthenium, iridium or rhodium oxideparticles (Japanese Patent Application Laid-open No. 9-302284) is alsoknown.

In addition, several cosmetic materials that utilize noble metals arealso known (Japanese Patent Application Laid-open Nos. 61-30511 and63-96112 and 2001-122723).

However, Japanese Patent Application Laid-open Nos. 61-30511 and63-96112 above use noble metals as pigments by utilizing theirdecorative effect, which is different from utilizing noble metals in theproduction process as function water or in similar forms. In JapanesePatent Application Laid-open No. 2001-122723 above, a cosmetic materialfor protecting the skin and activating its keratin layer is proposed,wherein such material is produced by dispersing platinum colloid in awater-based agent and the electric double-layer function of obtainedhigh-density, high-activity platinum colloid is used to improve theskin. However, this technology involves dispersion of platinum colloidvia chemical reduction of platinum ions in water, and no technology hasbeen available that melts noble metal in high-pressure water usingcombustion heat from a mixture gas of oxygen and hydrogen and alsoallows the obtained high-function water in which super-fine noble metalparticles are dispersed to be used as a cosmetic lotion.

DISCLOSURE OF THE INVENTION

The present invention aims to apply these almost infinite utilities ofnoble metals in bioactive materials, food materials, medical products,and so on-specifically in the production of cosmetic lotions, etc.

The present invention intends to melt noble metal in high-pressure waterusing a combustion gas of hydrogen and oxygen and cause the molten noblemetal to collide with high-pressure water to produce super-fine noblemetal particles, and also allow for use of the obtained high-functionwater containing micro-dispersed noble metal as a cosmetic lotion. Thepresent invention also intends to provide a method and apparatus forproducing the aforementioned cosmetic lotion, as well as a cosmeticmaterial containing the aforementioned cosmetic lotion as an activeingredient that acts upon the skin.

In the context of the present invention, noble metal refers to gold,silver, platinum, ruthenium, rhodium, palladium, osmium or iridium or analloy thereof, and “noble metal micro-dispersion water” refers to waterin which a very small amount of noble metal is dissolved in the state ofmicro-dispersed super-fine particles.

The basic characteristics of the present invention are explained by (1)through (6) below:

(1) A cosmetic lotion comprising noble metal micro-dispersion water inwhich super-fine noble metal particles are dispersed.

(2) A method for producing a cosmetic lotion in which super-fine noblemetal particles are dispersed, wherein a mixture gas of oxygen andhydrogen is burned in high-pressure water and the obtained combustiongas is used to melt noble metal, thereby allowing super-fine noble metalparticles to micro-disperse in water.

(3) An apparatus for producing a cosmetic lotion, comprising apressure-resistant container equipped with a high-pressure water tank,an injection nozzle for mixture gas of oxygen and hydrogen, a noblemetal bar, an ignition device and a combustion chamber.

(4) The apparatus for producing a cosmetic lotion as described in claim3, wherein a water electrolyzer for producing a mixture gas of oxygenand hydrogen is attached as an adjunct.

(5) A cosmetic material containing, as its water content, noble metaldispersion water in which super-fine noble metal particles aredispersed.

(6) The cosmetic material described in (5) above, which is a creamysoap, cosmetic lotion containing medicament, milky lotion, cream,shampoo, rinse, hair tonic or hair cream.

Here, a cosmetic lotion obtained by the present invention, made of noblemetal micro-dispersion water in which super-fine noble metal particlesare dispersed, is specifically a skin lotion or other cosmetic lotionthat contains the aforementioned micro-dispersion water of super-finenoble metal particles as the main ingredient and also has coloring andaromatic agents added as necessary. A cosmetic material is an aqueoussolution, milky lotion or cream in which a medicament acting upon theskin or hair is dispersed, and specific examples of such cosmeticmaterial include a creamy soap, cosmetic lotion containing medicament,milky lotion, cream, shampoo, rinse, hair tonic, hair cream or hairgrowth stimulant/hair tonic.

Generally in an aqueous dispersion solution or mixed solution in whichsuper-fine particles of noble metals are simply dispersed, the noblemetal settles and separates within a short period of time. The mostsignificant feature of the noble metal micro-dispersion water obtainedby the present invention is that the noble metal that has been melted bycombustion heat disperses in high-pressure water as super-fineparticles. Thus obtained micro-dispersion water does not cause the noblemetal to settle or otherwise separate from water over a long storageperiod, but allow it to remain micro-dispersed in a stable conditioninstead. The noble metal micro-dispersion water obtained by the presentinvention therefore exhibits the remarkable effect of providing abioactive cosmetic lotion or cosmetic material through an interaction ofwater molecules and super-fine noble metal particles, which could not beexpected from the conventional technologies.

In general, healthy skin retains 10 to 20% of water in its keratin layerto maintain the skin's suppleness. If the water content in the keratinlayer drops to 10% or less, the skin will become dry, and dullness,rough skin, generation of white powder comprising separated dead skincells, or chapped skin will result. To treat such skin, water and oilmust be replenished externally to restore a normal moisture/oil balancein the skin. On the other hand, hair is damaged by external irritationssuch as friction, heat from the sun, perm chemicals and inappropriatecuts, as well as by malnutrition caused by an unbalanced diet or drasticweight loss. Since damaged hair has no self-repairing ability, it mustbe protected externally to prevent further damage. Water and oil are twoimportant constituents of the skin and hair, and cosmetic lotions,treatment agents and hair growth stimulants are used to replenish waterand oil in our skin and hair.

In order to maintain supple skin, the skin's keratin layer retains thewater secreted from sweat glands or absorbed through the skin, whileevaporation of the retained water is prevented by the sebum cutaneum.Water is also absorbed into the hair cortex, which is a component ofhair, and adds moisture and a supple look to the hair while making thehair more flexible so as to let it bounce as the body moves. Oil formsan oil film over the hair cuticle and adds shine and gloss to the hairwhile minimizing friction and preventing damage to the hair cuticle.

The noble metal micro-dispersion water obtained by the present inventionhas been confirmed to provide excellent skin activation effects such asrepairing small cuts in the skin caused by razor blades, etc., as wellas remarkable repair effects on damaged hairs such as those having nickson the surface, which are not available with the cosmetic lotions ortreatment agents currently available in the market.

In addition to the aforementioned cosmetic lotion or cosmetic material,the aforementioned noble metal micro-dispersion water obtained by thepresent invention can also be utilized in health products such asmotor-function enhancing creams, medical products such as antibacterialagents, UV-protection products, healthy drinking water, healthsupplements, food preservatives, freshness-keeping agents for food,insect repellents, deodorants, and so on.

The mechanism as to why such noble metal micro-dispersion water in whichsuper-fine noble metal particles are dispersed, as obtained by thepresent invention, provides excellent bioactive functions is not yetclear. The inventors are working diligently to find scientificexplanations for these functions.

BEST MODE FOR CARRYING OUT THE INVENTION

A cosmetic material made of noble metal micro-dispersion water asobtained by the present invention or cosmetic lotion containing noblemetal micro-dispersion water as its water content is a new product notheretofore available. The present invention also provides a new methodand apparatus for producing a cosmetic material made of water thatcontains noble metal as super-fine particles, wherein the production ofsuch noble metal micro-dispersion water is based on melting noble metalnot through general methods that are commonly used to melt metal, but byusing heat generated from burning oxygen and hydrogen and causing theobtained molten noble metal to disperse in high-pressure water.

Specifically, after studying ways to efficiently and economicallyproduce a cosmetic lotion made of noble metal micro-dispersion water, aswell as ways to apply such micro-dispersion water to bioactivationpurposes, the inventors conceptualized a method to burn hydrogen andoxygen, insert a bar made of pure noble metal into the combustionatmosphere to heat the noble metal bar, and cause the obtained moltennoble metal to collide with high-pressure water and disperse in water assuper-fine particles, wherein such combustion of hydrogen and oxygen iscaused in high-pressure water so as not to produce substances other thanwater and noble metal.

The method proposed by the present invention requires that the amountsof hydrogen and oxygen to be burned, reaction pressure and feed rate ofnoble metal be controlled. In the aforementioned production method, anappropriate filter system is also necessary because not only super-finenoble metal particles but also a trace amount of fine particles of noblemetal oxide will be produced in water.

A method for producing a cosmetic material made of noble metalmicro-dispersion water as obtained by the present invention inhigh-pressure water through the aforementioned method, as well as anapparatus to embody this method, are explained according to thedrawings.

FIG. 1 is a production flow chart of a cosmetic lotion made of noblemetal micro-dispersion water as proposed by the present invention, whileFIG. 2 shows an apparatus for producing a cosmetic lotion made of noblemetal micro-dispersion water as proposed by the present invention.

The production apparatus for noble metal micro-dispersion water asproposed by the present invention (1), as shown in FIG. 2, comprises apressure-resistant container (2) for producing high-pressure water inwhich molten noble metal is dispersed, an electrolyzer/material gasgenerator (3) and a filter system to filter noble metal micro-dispersionwater (not illustrated).

The basic structure of the pressure-resistant container (2) proposed bythe present invention comprises a production apparatus for noble metalmicro-dispersion water in which super-fine noble metal particles aredispersed, wherein such apparatus comprising a high-pressure water tank(5), an injection nozzle for mixture gas of oxygen and hydrogen (14), acombustion chamber (6) and a noble metal bar (10). A water electrolyzer(3) for supplying material hydrogen and oxygen and a filter system thatfilters produced noble metal micro-dispersion water are attached asadjuncts.

The pressure-resistant tank (2) proposed by the present inventioncomprises the high-pressure water tank (5) made of metal, or preferablysteel. In this high-pressure water tank (5), a mixture gas of thehydrogen and oxygen generated by the electrolyzer (3) and suppliedthrough a hydrogen feed channel (16) and oxygen feed channel (17) isinjected at high pressure from an injection nozzle (14) into thecombustion chamber (6). The noble metal bar (10) is fed by a feedcylinder (13) into the combustion chamber (6) successively in accordancewith the melting amount of noble metal. The mixture gas of hydrogen andoxygen is ignited by an ignition device (11), and molten noble metal isreleased into high-pressure water (9). The molten noble metal collideswith high-pressure water and becomes super-fine particles, and thehigh-pressure water (9) containing these super-fine noble metalparticles is retrieved from the high-pressure water tank via an outlet(8) at the bottom of the tank and then filtered by an appropriate filtersystem (not illustrated).

As for the material gas generator (3), the hydrogen and oxygen producedby water electrolysis are pure gases, and therefore use of anelectrolyzer has the advantage of enabling an efficient supply ofcombustion gas of oxygen and hydrogen mixed at a theoretical ratio of 1to 2.

The present invention provides an example of generating hydrogen andoxygen via electrolysis of water (20) in the material gas generator (3),as material gases used in the production of noble metal micro-dispersionwater. A cathode and an anode are denoted as (18) and (18′),respectively. Hydrogen and oxygen may also be supplied directly to thehigh-pressure water tank (5) from respective cylinders.

This apparatus injects hydrogen and oxygen, generated via electrolysisand supplied through the hydrogen feed channel (16) and oxygen feedchannel (17), into the combustion chamber (6) from the nozzle (14) usinga pump, and causes the mixture gas to bum completely to achieve a stateof perfect steam gas of ultrahigh temperature. The pure noble metal bar(10) is inserted into this combustion gas to be heated and melted. Thenoble metal bar is inserted via the cylinder (13) at a constant rateaccording to the melting amount. To melt the noble metal bar, themixture ratio of hydrogen and oxygen must be strictly controlled at 2to 1. Also, a pressure regulating valve (7) must be provided to regulatethe pressure inside the high-pressure water tank.

The molten noble metal (12), heated to high temperature and thus meltedin the combustion chamber (6), is released from the combustion chamber(6) into high-pressure water (9), where the noble metal collides withthe high-pressure water to become super-fine particles. It is consideredthat a part of noble metal takes on a crystalline structure in thisprocess.

The produced super-fine noble metal particles in water have very stronghydrophobicity and therefore remain micro-dispersed in water in a stablecondition without settling even when a coagulating agent is added.

As for the operation of this apparatus, high-pressure hydrogen andoxygen are injected into the high-pressure water tank (5) from thenozzle (14) using a pump, the gas is ignited by the injection device(11) to achieve a state of perfect steam gas of ultrahigh temperature,and the pure noble metal bar (10) is successively inserted into thecombustion gas and melted.

In this apparatus, hydrogen and oxygen must be burned in high-pressurewater in impurity-free state so as not to produce substances other thanwater and super-fine noble metal particles. In addition, the positionwhere the noble metal bar is inserted must be where the mixture gas bumscompletely to achieve a state of complete steam gas of ultrahightemperature.

Other characteristics of the present invention include the refining ofthus produced noble metal micro-dispersion water, in which fineparticles of noble metal oxide are contained in addition to dispersedsuper-fine noble metal particles, in order to use the water as amaterial for cosmetic lotions and other cosmetic products as well ashealth products, food materials, drugs and quasi-drugs. So as not toremove the produced super-fine titanium particles more than necessary,filtering should preferably be implemented not by using ion exchange orreverse-osmosis membrane, but by using the filter system as explainedbelow that can yield noble metal micro-dispersion water suitable for adesired purpose. For example, filtering the high-pressure waterdischarged from the high-pressure water tank sequentially throughhollow-fiber membranes is beneficial in terms of enhancing thecharacteristics of noble metal micro-dispersion water and extending thefilter life, and such filter system will provide noble metalmicro-dispersion water that can meet the required standards governingthe aforementioned products.

The constituent analysis of noble metal micro-dispersion water asobtained by the present invention found a specified amount of super-finenoble metal particles and a very small amount of noble metal in thehigh-pressure water.

The analysis results of gold micro-dispersion water as obtained by thepresent invention are shown in FIG. 3.

EXAMPLE

An embodiment of the present invention is explained in details using anexample. Note, however, that the present invention is not limited tothis example.

FIG. 2 shows an example of the representative apparatus proposed by thepresent invention, wherein the apparatus comprises a high-pressure watertank (5), an injection nozzle for mixture gas of oxygen and hydrogen(14) and a material gold bar (10) and is used for producing a cosmeticlotion made of gold micro-dispersion water in which super-fine goldparticles, generated as a result of collision between molten gold andhigh-pressure water, are dispersed.

The high-pressure water tank (5) is a metal pressure-resistant tankproviding resistance under ultrahigh pressures, wherein a mixture gas ofhydrogen and oxygen supplied through the hydrogen feed channel (16) andoxygen feed channel (17) is injected into a combustion chamber (6)through the injection nozzle (14), and the gold bar (10) is fed into thecombustion chamber via a cylinder (13). The pressure inside thehigh-pressure water tank (5) must be controlled using a pressureregulating valve (7). The mixture gas is ignited by an ignition device(11), and the obtained molten gold (12) is released into, and collideswith, high-pressure water to become super-fine gold particles. Thusproduced gold micro-dispersion water in which super-fine gold particlesare micro-dispersed is retrieved from the tank via an outlet (8).

As for the operation of this apparatus, as mentioned above hydrogen andoxygen are fed under high pressure into the high-pressure water tank(5). The mixture gas is injected from the nozzle (14) and ignited by theignition device (11) to be burned completely to achieve a state ofperfect steam gas of ultrahigh temperature. The gold metal bar (10) isinserted into this combustion gas and melted. Gold (12), thus heated tohigh temperature and melted in the nozzle, is released into, andcollides with, high-pressure water to become super-fine gold particles.At this time, a part of gold takes on a crystalline structure, to whichgold atoms will rearrange themselves to form particles of near-sphericalshape, thus attaining an energetically stable state.

The produced gold micro-dispersion water contains super-fine goldparticles that remain in micro-dispersed state without using any activeagent. This water is retrieved from the outlet and fed to a filtersystem as appropriate. The filter system comprises filter membranes of50 microns, 25 microns, 3 microns, 0.5 micron and 0.1 micron, and bypassing the produced water through these filter membranes sequentially afinal gold micro-dispersion water containing a specified amount ofsuper-fine gold particles and a very small amount of dissolved gold isobtained.

It is appropriate to adjust the internal pressure of the production tankto approximately 2 atmospheres, feed rate of oxygen and hydrogen mixturegas (1:2) to 5 liters per second (3.5 atmospheres), and feed rate of thegold bar to 0.5 kg over two hours.

In the aforementioned production method, in order to produce one ton ofnoble metal micro-dispersion water a mixture gas of around 3.5atmospheres should be injected at approximately 4 to 6 liters per secondinto the high-pressure water tank containing water pressured to around1.5 to 2.5 atmospheres. An excessive gas pressure may damage thestructural components of the apparatus, while too low a pressure willcause water to enter the combustion chamber and allow the heated/meltednoble metal to dissipate into air in air bubbles, thus making less idealthe production condition of micro-dispersion water containing super-fineparticles.

As evident from the above test results, many of those who used the goldmicro-dispersion water obtained by the present invention cited improvedskin conditions such as suppler and smoother skin. Also, many of thosewho washed their hair with the gold micro-dispersion water orapplied/sprayed it to their hair cited reduction in fallen hair,increase in hair density, recovery of damaged hair, improved haircondition, smoother scalp, reduced dandruff and other improvements.Therefore, it is found that a cosmetic material made of goldmicro-dispersion water as obtained by the present invention would beeffective in improving the skin condition and promoting hair growth. Theskin activation effects of such water will likely help reduce andprevent skin pigmentations and also prevent aging of the skin, therebydelivering remarkable effects as drugs, cosmetics, and so on.

Although the above example described an example of using gold as thenoble metal, tests using other noble metals confirmed equivalenteffects.

Based on the confirmed effects of noble metal micro-dispersion water asexplained above, use of noble metal micro-dispersion water obtained bythe present invention as the water content for various cosmeticmaterials, instead of normal demineralized water, will likely producehigh-function cosmetic materials offering the efficacies of activeingredients contained in the cosmetic material as well as the effects ofnoble metal micro-dispersion water.
